On rate: Texas is friendlier for customers with a combined state + local rate of 8.19% vs 9.06%.
Neither state has a transaction-count trigger — only the dollar threshold matters.
Texas — nexus note
Texas sales tax nexus and SaaS taxability: economic nexus applies to remote sellers with $500,000 or more in total Texas revenue during the preceding twelve calendar months. After crossing that safe harbor, Texas requires a permit and sales/use tax collection no later than the first day of the fourth month after the threshold-crossing month. Texas treats data processing as a taxable service and the Comptroller says data processing providers include software-as-a-service sellers and application service providers; 20% of a data-processing charge is exempt, so SaaS treated as data processing is generally taxed on 80% of the invoice amount. Marketplace-only sellers whose marketplace provider certifies Texas collection generally do not need a Texas tax permit, but sellers must keep marketplace-sales records for at least four years.
Oklahoma — nexus note
Economic nexus in Oklahoma triggers at $100,000 in gross sales delivered into Oklahoma in the current or prior calendar year. No transaction count threshold.

Frequently asked questions
- Which state has the lower sales tax nexus threshold, Texas or Oklahoma?
- Oklahoma has the lower economic nexus threshold at $100,000, versus $500,000 in Texas. A seller's Oklahoma sales would reach the published Oklahoma threshold first. These are the thresholds published by each state's tax authority as of 2026-05-25; confirm against the official source before registering.
- Do both Texas and Oklahoma have marketplace facilitator laws?
- Yes. Both Texas and Oklahoma have marketplace facilitator laws, so marketplaces such as Amazon, Etsy, and eBay collect and remit sales tax on the sales they facilitate in both states.

- Which has the lower sales tax rate, Texas or Oklahoma?
- Texas has the lower combined state and local sales tax rate at 8.19%, compared with 9.06% in Oklahoma. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-05-25.
- Do I need to register for sales tax in both Texas and Oklahoma?
- It depends on where you cross each state's economic nexus threshold (or have physical presence there). Texas's published threshold is $500,000, and Oklahoma's is $100,000. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither.

- When did economic nexus take effect in Texas and Oklahoma?
- Texas's economic nexus rule took effect on 2019-10-01, and Oklahoma's took effect on 2019-11-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
